recommendations! Published in 2018 at "Geochimica et Cosmochimica Acta"

DOI: 10.1016/j.gca.2017.06.027

Abstract: Abstract Our goal is to compute the abundances of carbon atomic complexes that emerge from the C + O cores of core-collapse supernovae. We utilize our chemical reaction network in which every atomic step of growth employs… read more here.

DOI: 10.1051/0004-6361/202038784

Abstract: Context. In a previous paper we introduced a new method for simulating collisional gravitational N-body systems with linear time scaling on N, based on the Multi-Particle Collision (MPC) approach. This allows us to easily simulate… read more here.

DOI: 10.1093/mnras/staa3607

Abstract: We present measurements of the local core-collapse supernova (CCSN) rate using SN discoveries from the Palomar Transient Factory (PTF). We use a Monte Carlo simulation of hundreds of millions of SN light-curve realizations coupled with… read more here.

DOI: 10.1093/mnras/staa736

Abstract: Comparison of theoretical line profiles to observations provides important tests for supernova explosion models. We study the shapes of radioactive decay lines predicted by current 3D core-collapse ... read more here.

DOI: 10.1093/mnras/stab116

Abstract: We present 3D hydrodynamic simulations of neutrino-driven supernovae (SNe) with the PROMETHEUS-HOTB code, evolving the asymmetrically expanding ejecta from shock breakout until they reach the homologous expansion phase after roughly one year. Our calculations continue… read more here.

DOI: 10.1093/mnras/stab1353

Abstract: The analysis of current and future cosmological surveys of Type Ia supernovae (SNe Ia) at high redshift depends on the accurate photometric classification of the SN events detected. Generating realistic simulations of photometric SN surveys… read more here.

From the CMF to the IMF: beyond the core-collapse model

Sign Up to like & get
recommendations! Published in 2020 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/stab844

Abstract: Observations have indicated that the pre-stellar core mass function (CMF) is similar to the stellar initial mass function (IMF), except for an offset towards larger masses. This has led to the idea that there is… read more here.

DOI: 10.1093/mnras/stx534

Abstract: We study the morphologies of core collapse supernova remnants (CCSNRs) and find that about third of CCSNRs in our sample have two opposite `ears' protruding from their main shell. We assume that the ears are… read more here.

recommendations! Published in 2018 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/sty2094

Abstract: Optical and near-IR (NIR) line profiles of many ageing core-collapse supernovae (CCSNe) exhibit an apparently asymmetric bluewards shift caused by greater extinction by internal dust of redshifted radiation emitted from the receding regions of the… read more here.

recommendations! Published in 2018 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/sty3114

Abstract: The progenitor stars of core-collapse supernovae (CCSNe) are asymmetrically fluctuating due to turbulent convections in the late stages of their lives. The progenitor asymmetry at the pre-supernova stage has recently caught the attention as a… read more here.

DOI: 10.1093/mnras/stz262

Abstract: SN 2007bi and SN 1999as are among the first superluminous supernovae discovered. SN 2007bi was suggested to be powered by the radioactive decay of a large amount (5-10 M) of 56Ni. SN 1999as has a… read more here.
